| Abstract: | On the Reaction of Trifluorohalomethanes with Phosphanes The reactions of trifluorohalomethanes CF3X (X = Cl, Br, I) with Ph3P, Bu3P, (Me2N)3P, and (Et2N)3P were investigated. CClF3 does not react. In the reactions of CBrF3 and CF3I with Bu3P in acetonitrile trifluorophosphonium salts, [Bu3PCF3]X (X = Br, I), are formed, whereas gaseous CF3I and Bu3P yield Bu2PCF3. Depending on the reaction conditions the aminophosphanes form either [(R2N)3PX]X (R = Me, Et; X = Br, I) and CF3H or [(R2N)3PCF3]X. |
